Help - going on my 3rd Flywheel :(

[Kramer]

I will have to check on the intial timing later tonight (I think I should have the documents from the engine builder at home). However when the intial timing was set it had a carb on it. I was told that once the TWM set up was put on the Accel box controls the timing? (can't say I know exactly what that means though).

The other bolts were fine, just the head of one of the bolts was sheared off.

Dang... 1) I've never heard of shearing just one of the flywheel bolts off by its head. 2) I have never touched my hands to an Accel Engine Control Unit... but, if you had, say, 40+ degrees of timing at start up I guess you could eat up your starter and flywheel, maybe shear a bolt head too... maybe. With all that said, I do know that if you have your distributor setting not in synch with your timing table entries on the ECU screen you can get a ridiculous result. Like this: Accel gen7 Starting Problem - LS1TECH I guess, in theory, that could be the problem.

Or maybe something like this from the Accel DFI Instructions:

• Using a carbureted style distributor: If you are using a distributor from a carbureted engine that has centrifugal advance, you must lock down the advance and install an adjustable phase-able rotor (if possible) to prevent engine kickback while starting.
(Failure to do so will cause numerous issues that include: Broken starters, no start conditions, spark scatter and erratic timing).
